摘要
An apparatus and a method for detecting a narrow groove (72) of a specular reflection workpiece are provided. The apparatus includes: a spherical light source (3) configured to generate a uniform illumination on a workpiece surface (7); a laser array (4) having at least three lasers and configured to emit a laser light onto the workpiece surface (7); an imaging unit (5) configured to sample a light from the workpiece surface (7) to generate an image thereof; and a control unit (1) configured to control the spherical light source (3) and the laser array (4) to illuminate the workpiece surface (7) alternately, to control the imaging unit (5) to sample the image of the illuminated workpiece surface (7) respectively, to calculate a pose of a welding torch (8) with respect to the workpiece and a position of a center point of the groove (72) according to the image.
